A dryer for steel wire production

Abstract

This invention relates to a dryer for steel wire production, comprising a hot air blower and at least one section of a casing through which steel wire passes. A wiping component inside the casing can cover the circumferential surface of the steel wire. The drying mechanism includes a filter assembly, a pressurizing assembly, and a spraying assembly arranged sequentially along a manifold between the filter assembly and the hot air blower. The manifold in front of the filter assembly is connected to a return air duct extending into the casing. Multiple casings can be connected in series. The steel wire passing through the casing can be processed by the combined wiping component and the drying mechanism. During the circulating drying process via the return air duct, the hot airflow input from the hot air blower passes sequentially through the filter assembly with a self-cleaning function, and is then efficiently pressurized by the pressurizing assembly. Finally, the spraying assembly reheats the airflow and sprays clean, high-pressure hot airflow around the circumference of the steel wire. This significantly improves the drying and cleaning efficiency and effect of steel wires such as steel cords, effectively reduces the risk of scratches on the steel wire surface, and facilitates continuous production.

Description

Technical Field

[0001] This invention belongs to the technical field of steel wire drying equipment, specifically relating to a dryer for steel wire production. Background Technology

[0002] Steel wire is widely used in metal products. For example, steel cord, woven from steel wire, is an important component in tires and rubber products. During the production of steel cord, lubricants, moisture, or other contaminants adhere to its surface. The presence of these substances may negatively affect the quality and performance of the steel cord or the subsequent processing steps. Therefore, appropriate equipment is needed to dry and clean the steel cord. Compared to the traditional method of directly drying wire rods with hot airflow using a hot air blower, this drying method suffers from significant heat loss, high energy consumption, and low efficiency. Although some existing dryers employ internal circulating hot airflow, which improves the problem to some extent—for example, the steel wire circulating heating oven disclosed in CN210374448U uses multiple heat-conducting airflow pipes to blow hot airflow in the opposite direction as the steel wire passes through the drying chamber, and circulates the hot airflow to improve drying efficiency—the following problems and technical difficulties still exist:

[0003] (1) If multiple air outlets are used to blow hot air in one direction for drying, the contact surface between the hot air and the steel wire cannot completely cover the surface of the wire. The air volume on the windward side and the leeward side of the steel wire is significantly different, which will lead to uneven drying of the steel wire cord. Also, when there are many thick or highly adhesive contaminants on some parts of the steel wire surface, the hot air cannot clean them quickly due to the limited length of the dryer, which will also lead to poor cleaning effect of hot air drying or uneven drying of the steel wire.

[0004] (2) When the surface of the steel wire is dried with hot air, the source of the hot air may be the hot air that has been processed by other equipment and the heat energy has been recovered. The hot air itself contains a high content of solid dirt. This dirt will be sprayed out directly and scratch the surface of the steel wire. Or, due to the drying process, surface pollutants, impurities and other particulate matter or flocculent matter will be peeled off from the steel wire and enter the air duct with the circulating air duct. This peeled material will be sprayed out again with the hot air and scratch the surface of the steel wire. At the same time, as the drying operation continues, there is a risk of blocking the air outlet and stopping production. If only a filter screen, filter plate and other filter structure are simply set in the air duct, the size of the filter structure is large and it cannot be cleaned in time during continuous production to restore the filtration capacity, which is another problem.

[0005] (3) As the number of drying points increases or the drying location is required, the hot air flow pipeline is extended, which will cause some pipeline air pressure loss, or the total air velocity will decrease because the hot air flow is ejected and then merges with the circulation pipeline. This will result in a smaller hot air flow velocity ejected from the air outlet, which will weaken the effect of hot air flow eroding impurities on the steel wire surface, especially during continuous drying. The heat loss of hot air flow during circulation or transportation will also lead to a poor drying effect. Summary of the Invention

[0006] The present invention aims to at least partially solve one of the above-mentioned technical problems. The present invention provides a dryer for steel wire production, which can improve the drying and cleaning efficiency and effect, effectively reduce the risk of scratches on the surface of steel wire, and facilitate continuous production.

[0007] The technical solution adopted by this invention to solve its technical problem is:

The air distribution pipe in front of the filter assembly is connected to a return air pipe extending into the casing. The pressurizing assembly is used to increase the pressure of the hot airflow of the spraying assembly. The spraying assembly can spray hot airflow around the circumference of the steel wire.

[0009] Preferably, the device includes several chassis connected in series, and at least some of the chassis are provided with guide wheel assemblies, the guide wheel assemblies including guide wheels that cooperate with steel wires.

[0010] Preferably, the wiping component includes a plurality of wiping blocks arranged circumferentially around the steel wire, and the wiping blocks are provided with elastic support between them and the chassis.

[0011] Preferably, the filter assembly is provided with an air collector that also serves as an air collector, and the air collector is provided with several connecting pipes between it and the hot air blower.

[0012] Preferably, the filter assembly includes a filter housing, a filter plate, and a cleaning component. The filter housing is connected to the air duct and has at least one openable and closable ash discharge port. The filter plate covers the radial section inside the filter housing and is rotatably connected to a rotating shaft arranged along the axial direction of the filter housing. The rotating shaft has spiral blades. The cleaning component includes a scraper near the surface of the filter plate and is connected to the rotating shaft.

[0013] Preferably, the bottom of the filter housing is conical, corresponding to the spiral blades.

[0014] Preferably, the filter housing is axially slidably fitted with an annular baffle, and the annular baffle is provided with an outlet that can cooperate with the ash discharge port.

[0015] Preferably, the cleaning component includes a material support plate and a friction ring. The scraper is located below the filter plate and above the material support plate. One end of the material support plate is connected to a rotating shaft, and the other end of the material support plate is provided with an opening that corresponds to the ash discharge port. The material support plate is connected to a friction block that slides with the friction ring. The friction ring is connected to the filter housing.

[0016] Preferably, the material support plate is provided with a plurality of air guide holes.

[0017] Preferably, the return air duct is equipped with a one-way valve, and the pressurization assembly includes a ventilation duct, an elastic element, and a sliding element. The ventilation duct is connected to the air collection duct, and a boss is provided inside the ventilation duct. The elastic element is used to elastically support the sliding element on the boss. The sliding element can slide upward relative to the boss along the extension and retraction direction of the elastic element and cooperate with the boss to stop the ventilation of the ventilation duct. The sliding element can also slide downward relative to the boss along the extension and retraction direction of the elastic element and give way to the boss to maintain the ventilation of the ventilation duct.

[0018] Preferably, the sliding member is provided with at least one communicating hole, which can engage with or be recessed from the boss.

[0019] Preferably, the sliding member is connected to a limiting plate, and a pad is provided on the return air duct, the pad being located between the limiting plate and the sliding member.

[0020] Preferably, the ventilation pipe is provided with at least one limiting strip, which is slidably engaged with the sliding member to restrict the sliding member from sliding in the extension and retraction direction of the elastic member.

[0021] Preferably, the blowing assembly includes an outer cylinder and an inner cylinder, with an annular air duct connected to the air collection pipe between the outer cylinder and the inner cylinder, and a plurality of air outlets with an annular channel on the inner cylinder, through which steel wires pass.

[0022] Preferably, a heating wire is provided inside the annular air duct.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] (1) The present invention combines the wiping component with the drying mechanism. The wiping component covering the circumferential surface of the steel wire rubs the surface of the steel wire to wipe away surface stains and excess moisture, reducing the pressure of the drying mechanism. Then, the hot air is input by the hot air blower, and the hot air is sprayed around the circumference of the steel wire by the spraying component. This can effectively solve the problems of poor drying and cleaning efficiency and unevenness of the steel wire under the existing single hot air drying method.

[0025] (2) The drying mechanism of the present invention uses a filter component to filter out a large number of large particulate impurities or flocculent matter in the hot airflow. In particular, after wiping and continuous operation, it can effectively solve the problem that dirt directly or due to the hot airflow circulation spraying out can scratch the surface of the steel wire or block the spraying component.

[0026] (3) The filter assembly of the present invention uses the hot air flow to drive the spiral blade to rotate the shaft, drive the cleaning component to rotate, and use the scraper of the cleaning component to scrape off the impurities on the surface of the filter plate and drop them into the receiving plate for collection. When the ash discharge port is opened, the dust inside the receiving plate can be automatically cleared out under centrifugal action, which can further effectively solve the problem of not being able to clean in time to restore the filtration capacity in continuous production.

[0027] (4) When the cleaning component of the present invention rotates with the fixed sleeve, the friction block slides and rubs along the inner wall of the friction ring to generate static electricity and transfers the static electricity to the material support plate, so that the dust is attracted by the static electricity and stays in the material support plate, which can further effectively solve the problem of dust diffusion in the self-cleaning process of the filter component.

[0028] (5) The pressurizing component of the present invention is used to increase the hot air pressure of the blowing component, which can effectively solve the problem of poor drying effect caused by wind loss. When the air pressure decreases, the sliding member slides upward relative to the boss along the extension and retraction direction of the elastic member and cooperates with the boss to stop the ventilation of the ventilation pipe to increase the pressure. After pressurization, the sliding member slides downward relative to the boss along the extension and retraction direction of the elastic member and makes way for the boss to maintain the ventilation of the ventilation pipe to accelerate the flow rate of the hot air. This can further effectively solve the problem of high-efficiency pressurization of the pressurizing component.

[0029] (6) The spray assembly of the present invention introduces the accelerated hot airflow into the space between the outer cylinder and the inner cylinder, and then heats the hot air again through the heating wire. The heated hot air finally flows out from the air outlet. By heating nearby, the problem of the drying effect deteriorating due to the rapid loss of heat in the hot air can be further effectively solved. Attached Figure Description

[0042] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0043] In the description of this invention, it should be understood that the terms "circumferential," "radial," "upper," "lower," "axial," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.

[0044] In this invention, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] To address the issues of poor drying and cleaning effects in existing drying equipment due to its unidirectional hot airflow and air loss, as well as the problem of the hot airflow containing impurities scratching the steel wire, such as... Figure 1 As shown, this is a preferred embodiment of the dryer for steel wire production according to the present invention. The dryer includes a hot air blower 3 and at least one section of casing 1 through which the steel wire 10 passes. Figure 2 As shown, the housing 1 is equipped with a wiping component 8 and a drying mechanism 6. The wiping component 8 can cover the circumferential surface of the steel wire 10. An air distribution pipe 5 is provided between the drying mechanism 6 and the hot air blower 3. Figure 2 and Figure 3 As shown, the drying mechanism 6 includes a filter assembly 61, a pressurizing assembly 62 and a jetting assembly 63 arranged sequentially along the air collection pipe 5. The air collection pipe 5 in front of the filter assembly 61 is connected to a return air pipe 7 that extends into the machine casing 1. The pressurizing assembly 62 is used to increase the pressure of the hot air flow of the jetting assembly 63. The jetting assembly 63 can spray hot air flow around the steel wire 10 in a circumferential direction.

[0046] The aforementioned dryer, in operation, includes: conveying the steel wire 10 through the wiping component 8 and the blowing assembly 63 inside the casing 1; firstly, the wiping component 8 rubs against the circumferential surface of the steel wire 10 to initially wipe away or peel off strongly adhered dirt and impurities, or to remove excess moisture from the surface of the steel wire 10. Compared with existing single hot airflow drying methods, this reduces the subsequent drying burden, thereby improving drying and cleaning efficiency and effect within the limited length of the dryer; the hot airflow source is provided by the hot air blower 3, and after the hot airflow is input into the air duct 5, the filter assembly 61 filters out a large number of large particulate impurities or flocculent matter in the hot airflow. Especially when the dirt in the casing 1 increases after wiping and continuous operation, this effectively prevents dirt from being directly or sprayed out due to the circulation of hot airflow. The filtered hot airflow, pressurized by the pressurizing component 62, compensates for the wind loss during the conveying or circulation process. When the wiped steel wire 10 passes through the spraying component 63 again, the spraying component 63 can spray high-pressure hot airflow around the steel wire 10, allowing the hot airflow to fully contact the surface of the steel wire 10, quickly drying the moisture and oil stains on the surface of the steel wire 10, and eroding the dirt on the surface of the steel wire 10 under high pressure, further playing a drying and cleaning role. Therefore, compared with the existing single-direction hot airflow drying, the drying of the steel wire 10 can be more uniform, and the drying efficiency and effect are improved. The return air duct 7 is used to return the hot airflow in the casing 1 to the air collection duct 5, reducing the problem of excessive heat loss in the hot air leading to poor drying effect.

[0047] Preferably, it includes several chassis 1 connected in series, such as Figure 1 and Figure 2 As shown, at least part of the casing 1 is equipped with a guide wheel assembly 2. The guide wheel assembly 2 includes guide wheels 201 that cooperate with the steel wire 10. For example, the guide wheel assembly 2 can be set at both ends of the casing 1, and the guide wheels 201 can be installed above and below the steel wire 10. Especially when multiple casings 1 are connected in series, they are used to roll and cooperate with the steel wire 10, reducing wear while supporting and restricting the direction of the steel wire 10, so as to ensure proper wiping and drying. Multiple casings 1 used together can extend the drying time, which is more convenient than a long integrated casing. The chassis 1 also facilitates the installation, maintenance and replacement of internal components; when using chassis 1 alone, air blocking plates can be set at the head and tail ends of chassis 1 for the steel wire 10 to pass through, so as to reduce the loss of air pressure and heat energy due to the loss of hot airflow from both ends of chassis 1; when using multiple chassis 1 in a series, air blocking plates can also be set at the outer ends of chassis 1 at both ends; one hot air blower 3 can be used to supply air to multiple drying mechanisms 6 in chassis 1 to reduce energy consumption, or each drying mechanism 6 can be equipped with a hot air blower 3 for independent air supply, so as to control the temperature and pressure of hot airflow separately.

[0048] Preferred, such as Figure 2As shown, the wiping component 8 includes several wiping blocks arranged circumferentially around the steel wire 10. An elastic support 9 is provided between the wiping block and the housing 1. For example, the wiping block can be a rubber block with a certain elasticity, and the elastic support 9 can be a spring sheet arranged circumferentially around the steel wire 10. The two ends of the spring sheet are respectively connected to the housing 1 and the rubber block. Compared with the rigid connection between the rubber block and the housing 1, this elastic connection method can make the rubber block maintain reliable contact with the surface of the steel wire 10 under the elastic support of the spring sheet. When the thickness of the dirt on the surface of the steel wire is not uniform or there is a slight deviation in the conveying of the steel wire 10, the rubber block can still maintain close contact and relative friction with the steel wire, thereby improving the cleanliness and uniformity after wiping.

[0049] Preferred, such as Figure 2 As shown, the filter assembly 61 is provided with a collector duct that also serves as a collector duct 5. Several connecting pipes 4 are provided between the collector duct and the hot air blower 3. For example, when the hot air flow is increased to increase the filtration area of ​​the filter assembly 61, the size of the collector duct is larger than the output pipe size of the hot air blower 3. By adding multiple connecting pipes 4, the hot air flow can be evenly introduced into the collector duct, thereby making full use of the filtration surface of the filter assembly 61. Alternatively, the return air duct 7 can be connected to the collector duct to facilitate the installation of the return air duct 7. The outer wall of the return air duct 7 is fixedly connected and supported to the inner wall of the casing 1. Multiple return air ducts 7 can be set on the side of the collector duct to improve the return air efficiency.

[0050] Preferred, such as Figure 3 As shown, the jetting assembly 63 includes an outer cylinder 631 and an inner cylinder 632. An annular air duct 633 communicating with the air collection pipe 5 is provided between the outer cylinder 631 and the inner cylinder 632. The inner cylinder 632 is provided with several air outlets 634 of the annular channel, through which the steel wire 10 passes. For example, the top of the outer cylinder 631 is fixedly connected to the pressurizing assembly 62, the top of the pressurizing assembly 62 is fixedly connected to the filter assembly 61, the inner wall of the housing 1 is fixedly connected to the outer wall of the pressurizing assembly 62, and a fixing bracket 64 connected to the housing 1 is provided on the outside of the outer cylinder 631. The bottom of the fixing bracket 64 is connected to the housing 1. The inner wall of the inner cylinder 632 is fixedly connected to the inner wall of the outer cylinder 631, so that the blowing assembly 63 can be supported and installed. The gap between the outer cylinder 631 and the inner cylinder 632 forms an annular air duct 633 to evenly distribute the air volume to each air outlet 634. The air outlet 634 can be set as air holes spaced around the circumference of the inner cylinder 632, or as an annular slit around the circumference of the inner cylinder 632, so that when the steel wire 10 passes through the inside of the inner cylinder 632, the clean high-pressure hot air flow sprayed from the air outlet 634 can cover the circumference of the steel wire 10, thereby improving the drying efficiency and uniformity.

[0051] Preferred, such as Figure 3As shown, a heating wire 635 is provided inside the annular air duct 633. For example, the inner wall of the outer cylinder 631 is fixedly connected to both ends of the heating wire 635, and the heating wire 635 is wound around the outside of the inner cylinder 632. The heating wire 635 is used to further heat the hot airflow and prevent the temperature loss of the hot airflow during the conveying or circulation process from affecting the drying effect. This installation of the heating wire 635 close to the air outlet 634 can utilize the heating energy for drying more efficiently than placing the heating wire 635 in the air collection pipe 5 or the return air pipe 7.

[0052] Preferred, such as Figure 4 As shown, the filter assembly 61 includes a filter housing 611, a filter plate 612, and a cleaning component 613. The filter housing 611 is connected to the air duct 5. The filter housing 611 is provided with at least one openable and closable ash discharge port 6111. The filter plate 612 covers the radial section inside the filter housing 611. The filter plate 612 is rotatably connected to a rotating shaft 614 arranged along the axial direction of the filter housing 611. The rotating shaft 614 is provided with a spiral blade 615. The cleaning component 613 includes a scraper 6131 close to the surface of the filter plate 612. The scraper 6131 is connected to the rotating shaft 614.

[0053] For example, the top of the filter housing 611 is fixedly connected to the air collector, the edge of the filter plate 612 is fixedly connected to the inner wall of the filter housing 611, and the spiral is also installed at the bottom of the rotating shaft 614. When hot air enters the filter housing 611 of the filter assembly 61, the filter plate 612 can filter out impurities and particulate matter contained in the hot air, preventing impurities from flowing out with the hot air and scratching the surface of the steel wire 10 or blocking the air outlet 634, thus causing a decrease in the quality of the steel wire 10. When the hot air flows through the filter housing 611, the airflow is in the spiral blades The force on 615 drives the spiral blade 615 to rotate axially around the shaft 614, which in turn drives the shaft 614 and the cleaning component 613 on the shaft 614 to rotate for cleaning. The structure is compact and the size is small. If the scraper 6131 is set above the filter plate 612 and the ash discharge port 6111 is set to correspond to the scraper 6131 above the filter plate 612, the debris trapped above the filter plate 612 can be collected. After the ash discharge port 6111 is opened, the debris above the filter plate 612 can be cleaned, thus performing self-cleaning of the filter plate 612.

[0054] Preferred, such as Figure 4 As shown, the bottom of the filter housing 611 is conical, corresponding to the spiral blade 615. The conical design facilitates the acceleration of hot airflow when it passes through the bottom of the filter housing 611, which is more conducive to airflow pressurization and driving the spiral blade 615 to rotate.

[0055] Preferred, such as Figure 4As shown, the filter housing 611 is axially slidably fitted with an annular baffle 616. The annular baffle 616 is provided with an outlet 6161 that can cooperate with the ash discharge port 6111. The inner wall of the annular baffle 616 is slidably connected to the outer wall of the filter housing 611. The annular baffle 616 is rotated axially relative to the filter housing 611 until the outlet 6161 corresponds to the ash discharge port 6111, at which point the ash discharge port 6111 can be opened. When the annular baffle 616 is rotated until the outlet 6161 is misaligned with the ash discharge port 6111, the annular baffle 616 can be used to close the ash discharge port 6111. This is especially convenient when there are multiple ash discharge ports 6111, as it facilitates the simultaneous and rapid opening and closing of multiple ash discharge ports 6111.

[0056] Preferred, such as Figure 4 and Figure 5 As shown, the cleaning component 613 includes a material support plate 6132 and a friction ring 6133. The scraper 6131 is located below the filter plate 612 and above the material support plate 6132. One end of the material support plate 6132 is connected to the rotating shaft 614, and the other end of the material support plate 6132 is provided with an opening that corresponds to the ash discharge port 6111. The material support plate 6132 is connected to a friction block 6137 that slides with the friction ring 6133. The friction ring 6133 is connected to the filter housing 611.

[0057] For example, considering that placing the scraper 6131 above the filter plate 612 might scrape debris into the filter holes of the filter plate 612 and clog them, or push debris out of the filter holes under airflow pressure, thus impairing the filtration effect, it is preferable to install the scraper 6131 below the filter plate 612 near the lower surface of the filter plate 612. The scraper 6131 and the support plate 6132 are connected to the rotating shaft 614 via a fixing sleeve 6136. The support plate 6132 has a U-shaped cross-section, and the scraper 6131 is inclined and provided with several guide grooves 6135. The ends of the guide grooves 6135 correspond to the upper side of one side of the support plate 6132, and the upper side of the support plate 6132 is fixed. The filter housing 611 has a side baffle, and the inner wall of the filter housing 611 is slidably engaged with the side of the material receiving plate 6132 away from the fixed sleeve 6136. The outer wall of the friction ring 6133 is fixedly connected to the inner wall of the filter housing 611. When cleaning the filter plate 612, the rotating shaft 614 drives the scraper 6131 and the material receiving plate 6132 to rotate synchronously under the drive of the spiral blade 615. When the debris blocks the filter holes, the air pressure above the filter plate 612 squeezes the debris until it is exposed from below the filter holes. The rotating scraper 6131 continuously scrapes off the exposed debris. The debris rolls down along the inclined guide groove 6135 with the airflow and falls into the material receiving plate 6132 under the obstruction of the side baffle to complete the collection.

[0058] Simultaneously, the rotating support plate 6132, carrying the friction block 6137, slides along the inner wall of the friction ring 6133. During friction, the friction block 6137 generates static electricity, which is then transferred to the support plate 6132. At this point, dust and other debris are attracted by the static electricity and remain stationary within the support plate 6132, preventing them from being blown away by the wind. After a period of time, the annular baffle 616 is rotated so that its outlet 6161 is directly opposite the ash discharge port 6111. When the opening of the support plate 6132 aligns with the ash discharge port 6111, under the action of centrifugal force... The debris inside the material receiving plate 6132 can be discharged from the ash discharge port 6111, and the debris inside the material receiving plate 6132 is self-cleaned. Compared with the structure in which the scraper 6131 is set above the filter plate 612, the above-mentioned cleaning component 613 is more conducive to preventing debris from falling below the filter housing 611 during cleaning, making it easier for the filter plate 612 to self-clean quickly, making the operation simpler, and thus more conducive to improving the filtration and debris removal efficiency of the filter assembly 61, and especially in the process of continuous operation, it can quickly maintain and restore the filtration capacity of the filter plate 612.

[0059] Preferably, the material support plate 6132 is provided with a plurality of air guide holes 6134; for example, the air guide holes 6134 can be provided on both sides of the material support plate 6132 for air circulation, thereby reducing the wind resistance when the material support plate 6132 rotates, and facilitating the operation of the cleaning component 613.

[0060] Preferably, the return air duct 7 is equipped with a one-way valve. The one-way valve is used to ensure that the hot air in the casing 1 flows unidirectionally to the air duct 5, especially when the pressurization component 62 is installed, to prevent the hot air in the air duct 5 from flowing out of the return air duct 7 and affecting the air pressure and drying effect. Figure 3 and Figure 6 As shown, the pressurization assembly 62 includes a ventilation pipe 621, an elastic element 622, and a sliding element 623. The ventilation pipe 621 is connected to the air collection pipe 5. A boss 624 is provided inside the ventilation pipe 621. The elastic element 622 is used to elastically support the sliding element 623 on the boss 624. The sliding element 623 can slide upward relative to the boss 624 along the extension and retraction direction of the elastic element 622 and cooperate with the boss 624 to stop the ventilation of the ventilation pipe 621. The sliding element 623 can slide downward relative to the boss 624 along the extension and retraction direction of the elastic element 622 and give way to the boss 624 to maintain the ventilation of the ventilation pipe 621.

[0061] For example: the top of the ventilation duct 621 is fixedly connected to the bottom of the filter housing 611. The elastic element 622 is a compression spring, which is sleeved on the outside of the sliding element 623 and supported on the boss 624. The top of the sliding element 623 is supported on the top of the compression spring. When the air pressure in the ventilation duct 621 above the sliding element 623 is low, the sliding element 623 remains in a high position under the elastic support of the compression spring. The sliding element 623 and the boss 624 cooperate to cut off the ventilation of the ventilation duct 621. As the bottom diameter of the filter housing 611 gradually decreases, the cross-sectional area of ​​the airflow becomes smaller. Therefore, the airflow velocity increases when entering the ventilation duct 621. As the air pressure in the ventilation duct 621 above the sliding element 623 decreases, the airflow velocity increases. As the airflow inside the ventilator gradually increases and the internal pressure rises, the air pressure pushes the sliding member 623, forcing the compression spring to compress. The sliding member 623 slides downward relative to the boss 624 and makes way for the boss 624, maintaining ventilation in the ventilation pipe 621. The pressurized hot airflow can then be sent into the spray assembly 63, increasing the hot airflow pressure in the spray assembly 63 and thus improving the drying and erosion effects. Similarly, when the air pressure in the ventilation pipe 621 above the sliding member 623 decreases, the compression spring resets, causing the sliding member 623 to slide upward relative to the boss 624 and cooperate with the boss 624, thus cutting off the ventilation pipe 621 again to allow for pressurized spraying again. This pressurization assembly has a simple structure, compact design, and flexible operation.

[0062] Preferred, such as Figure 6 As shown, the sliding member 623 is provided with at least one connecting hole 6231. The connecting hole 6231 can cooperate with or be offset from the boss 624. For example, the sliding member 623 is cylindrical, the boss 624 is annular, and several connecting holes 6231 are spaced around the bottom side of the sliding member 623. When the sliding member 623 moves upward, the connecting hole 6231 cooperates with the boss 624 to close. When the sliding member 623 moves downward, the connecting hole 6231 is misaligned with the boss 624. Then, hot air can pass through the inside of the sliding member 623 and be ejected outward along the connecting hole 6231, entering the ventilation pipe 621 below the sliding member 623. This structure helps to increase the contact surface between the upper part of the sliding member 623 and the hot air flow, thereby increasing the operating sensitivity and stability of the pressurization component 62.

[0063] Preferred, such as Figure 6As shown, the sliding member 623 is connected to the limiting plate 625, and the return air duct 7 is provided with a pad 626. The pad 626 is located between the limiting plate 625 and the sliding member 623. For example, the sliding member 623 is provided with a fixing rod 627 inside, which connects to the limiting plate 625. The pad 626 is connected to the inner wall of the ventilation duct 621. The sliding member 623 drives the limiting plate 625 to move together through the fixing rod 627. When the outer wall of the limiting plate 625 contacts the pad 626, the sliding member 623 reaches its maximum stroke. This can prevent the compression spring from deforming too much and thus failing to complete the reset process. Alternatively, the pad 626 can be used to cooperate with the top of the sliding member 623 to limit the maximum upward stroke of the sliding member 623 and prevent the sliding member 623 from slipping upward due to the elastic force.

[0064] Preferred, such as Figure 6 As shown, the ventilation pipe 621 is provided with at least one limiting strip 628. The limiting strip 628 is slidably engaged with the sliding member 623 to restrict the sliding member 623 from sliding in the extension and retraction direction of the elastic member 622. For example, the top outer wall of the sliding member 623 is slidably engaged with the inner wall of the ventilation pipe 621, or it can be slidably engaged with the limiting strip 628 through the notch 6232. The limiting strip 628 can restrict the movement trajectory of the sliding member 623 to limit the rotation of the sliding member 623, so that the sliding member 623 is limited to sliding up and down, thereby improving the smoothness of operation.

[0065] In summary, the working principle of the aforementioned dryer for steel wire production can include:

[0066] In use, multiple housings 1 can be connected in series. The steel wire 10 is passed sequentially between the guide wheel sets 2 on both sides of the housing 1. During the transport of the steel wire 10, under the elastic force of the spring sheet, the rubber block rubs against the steel wire 10, cleaning its surface. The hot air blower 3 operates, sending hot air through the connecting pipe 4 into the air collector, which then sends the hot air into the drying mechanism 6. After entering the drying mechanism 6, the hot air first passes through the filter assembly 61, which filters out large particles of impurities. The filtered hot air then enters the pressurizing assembly 62, which increases the pressure of the hot air, thereby accelerating its flow rate. Finally, the spray assembly 63 sprays out clean, high-pressure hot air. Specifically:

[0067] When hot air enters the filter assembly 61, the filter plate 612 filters out impurities and particulate matter contained in the hot air, preventing impurities from flowing with the hot air and scratching the surface of the steel cord, thus reducing the quality of the steel cord. When the hot air passes through the conical part at the bottom of the filter housing 611, the hot air drives the spiral blade 615 to rotate while flowing. The spiral blade 615 rotates simultaneously, driving the scraper 6131 on the fixed sleeve 6136 to rotate via the rotating shaft 614. The rotation of the scraper 6131 scrapes off the impurities on the surface of the filter plate 612. Subsequently, the impurities on the surface of the filter plate 612 roll downward with the airflow and fall into the receiving plate 6132 under the obstruction of the side baffle. The friction block 6137 on 6132 slides along the inner wall of the friction ring 6133. During the friction process, the friction block 6137 generates static electricity and transfers the static electricity to the material support plate 6132, causing the dust to settle in the material support plate 6132 under the adsorption of static electricity, thus cleaning the filter plate 612. When the annular baffle 616 is rotated so that the outlet 6161 of the annular baffle 616 is aligned with the ash discharge port 6111 of the filter housing 611, the dust inside the cleaning component 613 can be cleaned, realizing the self-cleaning of the filter assembly 61. When the outlet 6161 of the annular baffle 616 is misaligned with the ash discharge port 6111 of the filter housing 611, the inside and outside of the filter housing 611 are not connected.

[0068] When the hot air enters the pressurization component 62, as the diameter of the conical bottom of the filter housing 611 gradually decreases, the cross-sectional area of ​​the airflow becomes smaller. Therefore, the airflow speed increases when it enters the ventilation pipe 621. As the airflow in the ventilation pipe 621 gradually increases, the pressure in the ventilation pipe 621 increases. At this time, the air pressure pushes the cylindrical sliding member 623 to slide down along the inner wall of the annular boss 624, and the compression spring is compressed. Then the hot air can be ejected outward through the connecting hole 6231.

[0069] When the hot airflow enters the spray assembly 63, the accelerated clean hot airflow enters the annular air duct 633 between the outer cylinder 631 and the inner cylinder 632. After being heated twice by the heating wire 635, it finally flows out from several air outlets 634 and sprays around the steel wire 10. The spray assembly 63 directly dries the steel wire 10.

[0070] After the spraying, the air pressure inside the casing 1 increases, which drives the opening of the one-way valve of the return air pipe 7, allowing some of the hot air inside the casing 1 to re-enter the air collector through the return air pipe 7, preventing the hot air from being lost too quickly. The steel wire 10 is continuously dried and cleaned under the action of the drying mechanism 6 of multiple series-connected casings 1, which can improve the drying and cleaning efficiency and effect, effectively reduce the risk of scratches on the surface of the steel wire 10, and facilitate continuous production.

All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
